stm32h735G_DK OB PCROP DMEP can't reset (un check)

[A1bucker]

Hello everyone, i am having issues with my board, I can't load to it. I am getting data read failed when i open stm32cubeprogrammer the OB PCROP DMEP box is checked (I did it) and I can't find a way to uncheck it. I have tried the ST-LINK_CLI.exe tool but it says it can't connect to the MCU. I fear I may have fried the controller.

Select RDP level 1 on (0xBB), hit apply.

Uncheck the DMEP box and select RDP level 0 (0xAA) on, hit apply.
